Letters Patent No.V l93,781, dated August 17, 1869.

STOVE AD FURNACE-G-RATE.

Tlxe Schedule referred to in these Letters Patent and making part of the same.

To all 'whom fit fina/y concern.-

Beit known that I, GEORGE A. WING, of Albany, in the county of Albany, and Stateof New York, have invented a new and improved Stove and Furnace-Grate; and I do hereby declare that the following is a full, clear, and exact description thereof,

lwhich will enable others skilled in the art to make and use the same, reference being had to the accom# panying drawings, forminga part of this specication,

in whichl Figure 1 is a top view of my invention.

' Figure 2 is a perspective view of one of the een# tres of the grate.

Figure 3 is a vertical central sect-ion.

Similar letters of reference indicate like parts in allv the figures.

The principal object of iny invention is'to construct a stove or furnacegrate that will, when rotated, clear out the ashes ii'oin the ire thoroughly.

This object I have accomplished by constructing a' grate with two or lnoreentres, and so connecting them, .that when one is shaken or rotated, they will all be simultaneously operated, and in like manner.

A designates the 'grate-frame, constructed of circular segments, as shown in fig. 1.

lllxtending across said frame A are' cross-bars B B, upon which the grate-centres C are supported.

To the central rotating grate C is attached a large toothed wheel, F, which. gears into or meshes with smaller toothed wheels Gr, which are pivoted to and revolve with the surrounding central grates C, as seen in figs. 1 and 3.

D designates a bar, projecting from and att-ached to the central pivot C of the grat-e.y

E designates the shaker of the stove, and shows the mode of operating the series of rotating grates.

The several rotating grat-es C are tinted or recessed, as shown at b in iig. 2, for the purpose of permitting a supply of air to the re, and also to form edges upon the gratas, the more readily to separate the ashes from the fire, when the grates are shaken.

A series of `three grates may be used to fit the long fire-box of cooking-stoves, or to forni an oval grat-e for an oval parlor-stove.d

For large furnaces, it is believed thatthis form or mode of constructionv offers great advantages over the present kinds of grates used.

These several grates Gnnght have loops connected to Vtheir pivots, and pins .working in slots in the loops, 4s o as to be operated by turning the central grate, theA same as in the above-described plan. But I prefer the mode, herein shown and described, of operating` the series 'of grates C, by means of the toothed wheels` F and Gl Itwill be 'seen from the above, that when the -centrl grate is rotated by means of shaking-bar E, all the surronmling grates C will alsobc rotated, and the tire will be well shaken by suoli an operation.

' lheouter ring A of the grate will rest upon a ring in the stove, atthc bottoni of the firepot, in the wellknown and usual manner, and in order to make it a dumping-grate, it will be necessary to have the ring A rest upon two pivots, placed at opposite points ol its circumference, in the well-known and usual man,

ner.

lVhat I claim as new, and desire to secure by Letters Patent, is-

The construction ot' a stove or tiirnacc-grate, consisting of a series of rotating grates, in combination with toothed wheels F and G, or their equivalents,

whereby the serios of grate-s C may be rotated similitaneonsly, substantially as herein set forth.

GEORGE A. W'ING.
